Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Hop production in a low‐trellis espalier system in the subtropical environment

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Hop cultivation (Humulus lupulus L.) is expanding into new regions, particularly under subtropical conditions. Traditionally, hop plants are trained using high‐trellis systems; however, a low‐trellis espalier structure may reduce establishment costs, facilitate phytosanitary management, and improve harvest uniformity.

Cauliflower Performance and Nitrogen Leaching Under Blends of Controlled Release and Conventional Urea

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 4, December 2026.
The efficiency of nitrogen fertilization in cauliflower depends on synchronizing nutrient availability with crop demand while minimizing environmental losses. This study evaluated cauliflower performance and nitrogen leaching under varying ratios of polymer‐coated controlled‐release urea (CRU) and conventional urea (CU).

Evapotranspiración de referencia estimada con Fao-Penman-Monteith, Priestley-Taylor, Hargreaves y RNA

Revista Mexicana de Ciencias Agrícolas, 2018
Las necesidades de agua de riego de los cultivos se basan en la estimación de la evapotranspiración de referencia (ETo) de cada zona en particular, están sujetas a la limitación de información meteorológica existente. El objetivo fue calcular ETo con FAO-Penman-Monteith (FAO-P-M), Hargreaves (H), Priestly-Taylor (P-T) y redes neuronales ...

Multi‐Timescale Drought Evolution in Greece (1960–2022) From Station‐Based SPI and SPEI

International Journal of Climatology, Volume 46, Issue 13, 15 November 2026.
Using homogenized data from 67 HNMS stations in Greece (1960–2022), we calculated SPI and SPEI at 1–12‐month scales to characterize meteorological to hydrological drought. We quantified the network‐based spatial extent of drought, compared SPI and SPEI drought signals, and tested changes with autocorrelation‐robust Mann–Kendall trends and Pettitt ...
